The DBH 1351 is a radial shaft seal that fits a housing bore of 125 mm and has a height of 12 mm. It keeps lubricant in place and blocks dust, water and other particles from reaching bearings and shafts. You will find this type of seal in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your application.

This seal carries an A 378 design, with a 125 mm outer housing and a 12 mm overall height. The data sheet lists a shaft diameter of 0 mm, which typically points to a seal with a large inner diameter or to a special designation that should be verified against the manufacturer's technical data. Before ordering, compare the shaft diameter in your equipment documentation with the data sheet. If anything is unclear, send us the drawing or the measured value and we will review it with you.

Seals of this type work where a rotating shaft passes through a fixed housing. They appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. They are also common in dusty or damp environments, where the sealing lip must hold up over long running cycles. When vibration or misalignment is present, consider a more flexible design or a seal with an additional spring.

Selection depends on rotation speed, working temperature and the lubricant in use. The lip and body materials must suit both the fluid and the surrounding conditions. At installation, make sure the housing is clean and free of burrs, apply lubricant to the lip before fitting it, and use an installation tool to avoid damage. Do not strike the lip directly. Once seated, check that the seal sits square to the shaft so sealing stays uniform.

If you need an equivalent size or a variant with a different shaft diameter, send part number 1351 or the dimensions of your current seal: shaft diameter, housing diameter and height. With that information we will look through our line of seals and oil seals for the closest match. We can also assist when mounting space is tight or when the equipment runs under severe conditions. MR Industrial Accessories supplies power transmission and sealing components.
